Backups failing to connect to mysql

Hi,

For some time now my backups only complete partially. Based on the messages in the emails, seems like they are failing on connecting to mqsql. Here is the error log:

Backup is partially complete. Final size was 726.97 KiB. Total backup time was 00 minutes, 52 seconds.

.. backup of mysql failed : mysql::execute_sql failed : DBI connect failed :  Can't connect to local MySQL server through socket '/var/run/mysqld/mysql.sock' (2)

On inspecting the Webmin MySQl Database server, I am seeing this error over there:

Error! MySQL is not running on your system - database list could not be retrieved.

MySQL error messageThe full MySQL error message was : DBI connect failed : Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysql.sock’ (2)

Not sure if these are related. Any ideas on how I can go about troubleshooting this?

Thank you!
K
